Capability acquisition method and device, capability indication method and device

technical field

The present disclosure relates to the field of communication technologies, and in particular, to a capability acquisition method, a capability indication method, a capability acquisition apparatus, a capability indication apparatus, a communication apparatus, and a computer-readable storage medium.

Background technique

During the communication between the base station and the terminal using the beam, the base station may determine the transmit beam corresponding to each receive beam used by the terminal according to the beam management.

The terminal can measure the reference signal (for example, the channel state information reference signal CSI-RS) in each transmit beam separately through each receive beam, determine the optimal transmit beam corresponding to each receive beam according to the measurement result, and form an optimal transmit beam for each receive beam. The beam pair indicating the receive beam and the transmit beam is sent to the base station, the base station determines the transmit beam corresponding to each receive beam according to the beam pair, and then configures the base station to use the receive beam to receive the corresponding transmit beam.

For example, the terminal has 4 receiving beams and the base station has 8 transmitting beams, then the terminal can receive the reference signal in each transmitting beam through the 4 receiving beams respectively, then for each receiving beam, 8 measurement results can be obtained, and then From the eight measurement results, the transmit beam corresponding to the optimal result can be determined as the best transmit beam of the receive beam.

Therefore, for the 4 receiving beams, 4 beam pairs can be determined and sent to the base station, and the base station can determine the transmit beam corresponding to each receiving beam according to the received 4 beam pairs. For example, one beam pair in the 4 beam pairs is expressed as (T6, R3), indicating that the receiving beam marked 3 corresponds to the transmitting beam marked 6, then the base station can configure the terminal to use the receiving beam marked 3 to receive the signal sent by the transmitting beam marked 6.

However, the above process is mainly applicable to the case where a single transmit beam transmits a single carrier. In a carrier aggregation scenario, a single transmit beam can transmit multiple carriers at the same time, and some problems will arise in this case.

Detailed ways

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

In the carrier aggregation scenario, the base station can send multiple component carriers CC (component carrier) to the terminal at the same time, and the terminal can use the receiving beam to receive multiple component carriers at the same time, and which beam the terminal uses to receive which component carrier is configured by the base station of.

Similar to the beam management mechanism in the related art, each component carrier sent by the base station also carries a reference signal. The terminal can measure the reference signal in each component carrier through each receiving beam, and determine each component according to the measurement result. The receiving beam corresponding to the carrier, the corresponding relationship between the receiving beam and the component carrier is generated and reported to the base station.

For example, the terminal has 4 receiving beams, referred to as beam R1, beam R2, beam R3 and beam R4, and the base station can simultaneously transmit 5 component carriers to the base station, referred to as CC1, CC2, CC3, CC4 and CC5. The terminal measures the reference signals in the 5 CCs through 4 beams respectively, and the obtained result is that R1 is used to receive CC1 and CC2, R2 is used to receive CC3, and R3 is used to receive CC4 and CC5. Then, the base station can configure the terminal to receive CC1 and CC2 through R1, CC3 through R2, and CC4 and CC5 through R3 according to the correspondence between the receiving beam and the component carrier reported by the terminal.

However, the premise of implementing the above solution is that the terminal can use at least three beams as receiving beams at the same time to receive component carriers. However, the maximum number of receive beams that can be supported by different terminals for simultaneous reception is different. For example, in the case that the above-mentioned terminal only supports the simultaneous use of 2 receive beams for reception at most, if the base station continues to configure the 5 CCs sent at the same time The 3 receive beams for the terminal will cause problems in the reception of the CC.

FIG. 1 is a schematic flowchart of a method for acquiring a capability according to an embodiment of the present disclosure. The capability acquisition method shown in this embodiment may be applicable to base stations, and the base stations include but are not limited to 4G base stations, 5G base stations, and 6G base stations. The base station may communicate with a terminal serving as user equipment, and the terminal includes but is not limited to communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices.

It can be understood by those skilled in the art that the technical solutions of each embodiment can be implemented independently or together with any other technical solutions in the embodiments of the present disclosure, which are not limited by the embodiments of the present disclosure.

In one embodiment, the terminal may be a terminal to which the capability indication method described in any subsequent embodiment is applicable.

As shown in Figure 1, the capability acquisition method may include the following steps:

In step S101, acquiring capability information from a terminal;

In step S102, according to the capability information, determine a first number of receiving beams that the terminal can support at most and used for receiving at the same time.

In one embodiment, the terminal may determine how many receiving beams it can use simultaneously for reception at most, and carry the determined number of receiving beams as the first number in capability information and send it to the base station.

After the base station receives the capability information, it can determine that the maximum number of receive beams that the terminal can support that can be used for reception at the same time is the first number, that is, the terminal can use the first number of receive beams at the same time to receive the component carriers simultaneously sent by the base station. .

In one embodiment, the method further includes:

Sending indication information to the terminal to instruct the terminal to report the capability information.

When the base station needs to acquire capability information, it may first send indication information to the terminal, and instruct the terminal to report the capability information through the indication information. After receiving the indication information, the terminal can send the capability information to the base station.

It should be noted that the terminal may also automatically report the capability information to the base station without receiving the indication information, for example, during the process of establishing a connection with the base station (eg, the random access process), the capability information is reported to the base station.

FIG. 2 is a schematic flowchart of another capability acquisition method according to an embodiment of the present disclosure. As shown in Figure 2, in some embodiments, the method further includes:

In step S201, determining a second number of candidate beams that need to be configured for the terminal and are simultaneously used for receiving carriers;

In step S202, the terminal is configured with receiving beams simultaneously used for receiving carriers according to the first number and the second number.

In one embodiment, the terminal may measure each carrier sent by the base station separately, and according to the measurement result, a candidate beam for receiving each of the carriers may be determined among the beams available to the terminal.

Still take the above-mentioned four beams R1, R2, R3, R4 and five component carriers CC1, CC2, CC3, CC4 and CC5 as an example. It should be noted that, the carrier in all embodiments of the present disclosure may refer to a component carrier in carrier aggregation.

For example, according to the measurement result, the terminal determines that R1 is used to receive CC1 and CC2, R2 is used to receive CC3, and R3 is used to receive CC4 and CC5, and then R1 can be corresponding to CC1 and CC2, R2 can be corresponding to CC3, and R3 can be corresponding to CC4 and CC5. sent to the base station. The base station may determine that by configuring the terminal to simultaneously receive component carriers through three receiving antennas, five component carriers can be received, that is, the second number is three.

However, the problem is that the terminal can actually support at most the first number of carriers used for reception at the same time, which may not necessarily satisfy the terminal using the second number of beams for reception at the same time.

According to this embodiment, the base station not only configures the terminal for receiving beams simultaneously used for receiving according to the second number, but comprehensively considers the first number and the second number to configure the terminal for receiving beams that are simultaneously used for receiving carriers.

For example, in the case where the first number is greater than or equal to the second number, the terminal can actually use the first number of beams to receive at the same time, which can satisfy the second number of beams that the base station needs to configure for the terminal to receive at the same time, then The base station may configure the terminal to use the second number of beams to simultaneously receive component carriers according to the two numbers of beams that are configured for the terminal at the same time as needed. Accordingly, it can be ensured that the configuration result satisfies the quantity that the base station needs to configure for the terminal and is used for reception at the same time, thereby ensuring a good communication effect between the base station and the terminal.

For example, in the case where the first number is less than the second number, the terminal can actually use the first number of beams to receive at the same time, but cannot meet the second number of beams that the base station needs to configure for the terminal to receive at the same time, then the base station will The terminal cannot be configured to use the second number of beams to simultaneously receive component carriers according to the two numbers of beams simultaneously used for reception configured for the terminal, and at most the terminal can only be configured to use the first number of beams to simultaneously receive component carriers. According to this, it can be ensured that the configuration result is within the range of the maximum number of beams that the terminal can support at the same time for reception, and the configuration result is as close as possible to the number of beams that the base station needs to configure for the terminal and used for reception at the same time. better communication between them.

In one embodiment, the method further includes:

Determine the carrier that each of the candidate beams needs to receive.

In one embodiment, in addition to the above-mentioned first quantity, the capability information can also carry an identifier of each beam in the first quantity of beams, and an identifier of a carrier to be received by each beam. The base station can determine the correspondence between the candidate beams and the carriers according to the identifier of the beam and the identifier of the carrier, and then can determine the carrier to be received by each candidate beam. For example, the correspondence between beams and identifiers can be shown in Table 1:

载波标识carrier identification	波束标识Beam ID
CC1、CC2CC1, CC2	R1R1
CC3CC3	R2R2
CC4、CC5CC4, CC5	R3R3

Table 1

According to Table 1, the base station can determine that R1 is used to receive CC1 and CC2, R2 is used to receive CC3, and R3 is used to receive CC4 and CC5. However, in fact, the maximum number of beams that the terminal can support for receiving carriers at the same time may be different from the beams in the above correspondence. Therefore, the base station also needs to determine, according to the capability information, how many beams the terminal can actually use at the same time to receive carriers.

For example, the candidate beams corresponding to the above 5 carriers are R1, R2 and R3. If the base station determines that the terminal can use 4 beams to receive carriers at the same time according to the capability information, and the 4 beams are R1, R2, R3 and R4, then the base station can configure The terminal uses R1, R2, and R3 as receiving beams.

By determining the carrier to be received by each candidate beam, the base station can select the candidate beam corresponding to the carrier to be sent as the receiving beam as much as possible when configuring the receiving beam for the terminal at the same time, so as to ensure the best communication effect. .

FIG. 3 is a schematic flowchart of yet another capability acquisition method according to an embodiment of the present disclosure. As shown in FIG. 3 , in some embodiments, configuring the terminal according to the first quantity and the second quantity to simultaneously use receive beams for receiving carriers includes:

In step S301, in response to the first number being less than the second number, determining the first number of target beams and a third number of remaining beams other than the target beams in the candidate beams;

In step S302, it is determined to receive the first measurement result of the corresponding carrier through the target beam, and to receive the second measurement result of the corresponding carrier through the remaining beam;

In step S302, a receive beam is configured for the terminal according to the absolute value of the difference between each of the second measurement results and each of the first measurement results.

In one embodiment, when the first number is less than the second number, the terminal can actually use the first number of beams for simultaneous reception, which cannot satisfy the second number of beams that the base station needs to configure for the terminal for simultaneous reception. number, then the base station cannot configure the terminal to use the second number of beams to receive component carriers at the same time according to the number of beams that need to be configured for the terminal at the same time. carrier.

In this case, the base station may first determine the first number of target beams in the candidate carrier, and the remaining beams other than the target beam in the candidate carrier, and the number of the remaining beams is the third number.

For example, the base station determines that R1 is used to receive CC1 and CC2, R2 is used to receive CC3, and R3 is used to receive CC4 and CC5, and the terminal only supports at most 2 beams for reception at the same time. These 2 beams are R1 and R3, then the base station It can be determined that the candidate beams are R1, R2 and R3, the target beams are R1 and R3, and the remaining beams are R2.

Further, the terminal may determine to receive the measurement result of the corresponding carrier through the target beam, which is called the first measurement result, and receive the second measurement result of the corresponding carrier through the remaining beam, which is called the second measurement result.

For example, the carriers corresponding to R1 are CC1 and CC2, and the first measurement result includes the measurement result for CC1 and CC2, which is referred to as P1 for short. For example, the first measurement result may be the result obtained by measuring the CSI-RS in CC1 and the CSI-RS in CC2, and the CSI-RS of the two CCs may be measured separately through R1, and then the two measurement results are integrated (for example, weighted and ) to obtain the first measurement result P1.

For example, the corresponding carriers of R3 are CC4 and CC5, and the first measurement result further includes the measurement result for CC4 and CC5, which is referred to as P3 for short. For example, the first measurement result may be the result obtained by measuring the CSI-RS in CC4 and the CSI-RS in CC4, and the CSI-RS of the two CCs may be measured separately through R3, and then the two measurement results are integrated (for example, weighted and ) to obtain the first measurement result P3.

For example, the carrier corresponding to R2 is CC2, and the second measurement result is the measurement result for CC3, which is referred to as P2 for short. For example, the second measurement result may be a result obtained by measuring the CSI-RS in CC3.

Then the first measurement results obtained are R1 and R3, and the second measurement results obtained are R2. Of course, the number of first measurement results is not necessarily two, and the number of second measurement results is not necessarily one. It can also be one or more.

The base station can configure the receiving beam for the terminal according to the absolute value of the difference between each second measurement result and each first measurement result. The absolute value of the difference is taken, and the absolute value of the difference can represent the relationship between the beams corresponding to the measurement results. The smaller the absolute value of the difference, the smaller the difference between the beams corresponding to the measurement results. The difference between the beams, the smaller the difference between the beams, the smaller the angle between the beams.

Therefore, for the second measurement result, the target beam with the smallest difference between the remaining beams corresponding to it can be selected to receive the corresponding carrier. For example, the remaining beam corresponding to P2 is R2, and the carrier corresponding to R2 is CC3. The smallest difference in R2 is R1, then the terminal can be configured to use R1 as the receiver of CC3 to receive CC3.

Accordingly, it can be ensured that the difference between the configured target beam and the remaining beams is the smallest, so that the effect of receiving the carrier corresponding to the remaining beams is not very bad, which is beneficial to ensure the communication quality.

It should be noted that the above measurement results may be characterized by reference signal received power RSRP, reference signal received quality RSRQ, and the like.

FIG. 4 is a schematic flowchart of yet another capability acquisition method according to an embodiment of the present disclosure. As shown in FIG. 4 , configuring the receiving beam for the terminal according to the absolute value of the difference between each of the second measurement results and each of the first measurement results includes:

In step S401, the i-th second measurement result in the third number n of the second measurement results is determined, and the m differences of each of the first measurement results in the second number m of the first measurement results The absolute value of the value, i takes values from 1 to n;

In step S402, the target beam corresponding to the smallest absolute difference value among the m absolute difference values is configured as the receiving beam of the required receiving carrier corresponding to the i-th second measurement result corresponding to the remaining beams.

In one embodiment, when the first quantity is less than the second quantity, for example, the first quantity is m+n and the second quantity is n, then the third quantity is the difference m between the first quantity and the second quantity, Then the base station configures the receiving beam for the terminal according to the absolute value of the difference, that is, the configuration is performed in the case of n remaining beams and m target beams. Accordingly, there are n second measurement results and m first measurement results. .

In this case, for any second measurement result among the n second measurement results, called the i-th second measurement result, the difference between it and each first measurement result can be calculated to obtain m difference. i takes values from 1 to n, that is, for each second measurement result, the absolute value of the difference is calculated according to the above method, then for n second measurement results and m first measurement results, a total of m × n absolute value of difference.

For the i-th second measurement result, in the calculated absolute values of m difference values, the target beam corresponding to the smallest absolute value of the difference value can be determined as the ith second measurement corresponding to the remaining beams required to receive the carrier. receive beam.

For example, P1, P2 and P3 above, the absolute value of the difference between P1 and P2 is called com1, and the absolute value of the difference between P3 and P2 is called com2. Among these two absolute differences, the smallest absolute difference is com1 and com1. The corresponding target beam is R1, that is, the difference between R1 and R2 is the smallest. Therefore, R1 can be configured as the receiving beam of R2 to receive the carrier CC3, so that the terminal can use R1 to receive CC1, CC2 and CC3.

Accordingly, it can be ensured that the difference between the target beam configured to receive the carrier corresponding to the remaining beam and the remaining beam is minimal, so that the effect of receiving the carrier corresponding to the remaining beam is less different from the effect of receiving the carrier through the remaining beam, which is conducive to ensuring good communication quality.
